As sibling said, using the mautrix bridges. I started with just bridge mode I think, and then switched to puppet mode, which seemed to integrate much better. Pictures and everything work fine.
However, you have to maintain a homeserver, which is not for everyone. If wouldn't have one already, I would just pay the element.io service which includes bridging (but I haven't tried it out).
